Even as the National Investigation Agency on Saturday arrested 13 terror suspects, believed to be sympathisers of the IS following raids across 12 locations in the country, including Mumbai, there is a serious threat perception in the run up to Republic Day.

The French consulate in Bengaluru had received a threat letter on January 11, warning against French President Francois Hollande visiting India to be the chief guest at the Republic Day parade.

Even as security is upped across the country during Republic Day or Independence Day, this year a new turn of events has raised threat perceptions even more. With army stickers being stolen from windscreens of vehicles, army and police vehicles stolen, the nation has put on an all-time security alert.

An internal study by the Intelligence Bureau shows that terrorists are moving from hoax calls to car thefts to send security agencies in a tizzy.

To battle this, a new device is being considered to prevent carjacking of army and police vehicles -- a biometric locking system using fingerprints. Security experts believe this will put an end to vehicles being stolen. 

It remains to be seen how soon this is implemented.
